I'd go to Beckett dot com and search for it. Even if you're not a member, it should tell you if there is pricing for the card or not. If you are a member and logged in, then you'll see the price. If you're not a member or not logged in, then it will have a link to "buy pricing".
That only works with sets in Beckett's system and Beckett gave up on including a great many non-mainstream sets after about 2004. Now that COMC is accepting properly formatted checklist submissions, I'd love to know if there's way to tell whether or not the checklist has been added to the system before I send any cards from that set.
